We really liked Arhi's SID gen 3...so we decided to build our own. We allready build a Version 1 which was based on his gen2 but a few bugs were found out, and corrected. so now here is the Soldering Iron Driver V1.5. Its based on arhis Gen3.Read about his project, and development here...viewtopic.php?f=56&t=2457Read about our version here:http://dangerousprototypes.com/docs/Pat ... evelopment

This driver is capable of driving all soldering irons based on RTC, J or K type thermocouples...ITs been tested on Hakko, Gordak, Solomon, and Weller soldering irons....

Well, if it was single sided it could not have nice ground under the analog input... also you can always make 2 sided board at home and solder parts on both sides :D, not that you never did it :D

The major issue I had with encoders is the freaking button. I have some encoders with buttons at home and the "softest" one requires 0.7 kg of force to press the darn button ... (the other ones require more then 1 kg) ..

I never used joysticks on my electronics, I was tempted few times... anyhow for soldering iron I think encoder is way better choice as 99% of the time you will be only rotating it, the button is used only if you go trough menus (calibration, startup options etc..) so it's not crucial...

jup its the ntc...although I would advise you to wait a while before building anything as there is no firmware that suports the board, jet, if you are familiar with writing your own firmware, you could extrapolate from arhis gen3 driver, only watch out as he uses a different pinout...

there are also errors on this board you should be avare, it does not support RTD type irons, hakko/gorak...etc. it only supports k-type sensor stuf...also firmware for it most probably wont be built. the reason for this is that we rushed these prototype boards before arhi figured out there were issues with his gen2(on which this was based) in the mean time Arhi updated his to gen3, and we did as well,our V1.5 corresponds with arhis Gen 3....sorry for the inconvenience..

If you need any help figuring stuff out, and continue to build the board, I am here to answer any questions...

I could try to write my own firmware, I read that arhi posted a little hack to support Hakko-like soldering irons on the gen 2. However i have to wait because i don't have all the components yet.Can you tell me the value of the NTC?
